ive got some funds and i want to put them into an air/fuel controller. i recently put in a wideband o2 sensor and now i want to put it to use on a dyno tune. the thing is i dont know much about this sort of thing. the only thing ive heard somewhat good things about was the safc 2. but i want to get some advice from someone who has atleast used an air/fuel controller before i buy one.
thanks in advance.
